(WIP) Release Notes - Mesos - Version 0.23.0
--------------------------------------------
This release contains several new features:
* Support for launching tasks/executors on revocable resources. These
resources can be revoked by Mesos at any time, causing the tasks
using them to be throttled or preempted.
* API Changes:
* [MESOS-2654] - A new 'capabilities' field has been addd to FrameworkInfo
to opt in to revocable resources.
Release Notes - Mesos - Version 0.22.1
--------------------------------------
* This is a bug fix release.
** Bug
* [MESOS-1795] - Assertion failure in state abstraction crashes JVM.
* [MESOS-2161] - AbstractState JNI check fails for Marathon framework.
* [MESOS-2583] - Tasks getting stuck in staging.
* [MESOS-2592] - The sandbox directory is not chown'ed if the
fetcher doesn't run.
* [MESOS-2601] - Tasks are not removed after recovery from slave and mesos
containerizer
* [MESOS-2643] - Python scheduler driver disables implicit acknowledgments by
default.
* [MESOS-2668] - Slave fails to recover when there are still processes left in
its cgroup
** Improvement
* [MESOS-2461] - Slave should provide details on processes running in its
cgroups
** Task
* [MESOS-2614] - Update name, hostname, failover_timeout, and webui_url
in master on framework re-registration
Release Notes - Mesos - Version 0.22.0
--------------------------------------
This release contains several new features:
* Support for explicitly sending status updates acknowledgements from
schedulers; refer to the upgrades document for upgrading schedulers.
* Rate limiting slave removal, to safeguard against unforeseen bugs leading to
widespread slave removal.
* Disk quota isolation in Mesos containerizer; refer to the containerization
documentation to enable disk quota monitoring and enforcement.
* Support for module hooks in task launch sequence. Refer to the modules
documentation for more information.
* Anonymous modules: a new kind of module that does not receive any callbacks
but coexists with its parent process.
* New service discovery info in task info allows framework users to specify
discoverability of tasks for external service discovery systems. Refer to
the framework development guide for more information.
* New '--external_log_file' flag to serve external logs through the Mesos web UI.
* New '--gc_disk_headroom' flag to control maxmimum executor sandbox age.
* API Changes:
* [MESOS-1143] - TASK_ERROR is now sent instead of TASK_LOST when rescheduling
a task should not be attempted.
* [MESOS-2086] - Update messages.proto to use a raw bytestream instead of a
string for AuthenticationStartMessage.
* [MESOS-2120] - Task labels which enable key value pairs in task info which
follows them through the task life-cycle.
* [MESOS-2185] - Slave state.json will now include custom resource types in
addition to first-class resource types.
* [MESOS-2208] - Service discovery info for tasks and executors.
* [MESOS-2322] - All arguments can now read their values from a file, just
specify --name=file://path/to/file.
* [MESOS-2347] - The C++/Java/Python APIs have been updated to provide the
ability for schedulers to explicitly send acknowledgements.
TaskStatus now includes a UUID to enable this.
* Deprecations:
* [MESOS-444] - Slave checkpoint flag has been removed as it will be enabled
for all slaves.
* [MESOS-1876] - Remove deprecated 'slave_id' field in ReregisterSlaveMessage.
* [MESOS-2058] - Deprecate stats.json endpoints for Master and Slave and task
status counts from state.json. See /help/metrics endpoint for
more information.
* [MESOS-2322] - Deprecated specifying JSON blobs to parse using an absolute
path to point at the filename.
This release also includes several bug fixes and stability improvements.
** Technical task
* [MESOS-2263] - Enable protobuf::write to handle google::protobuf::RepeatedPtrField<T>
* [MESOS-2264] - Enable protobuf::read to handle google::protobuf::RepeatedPtrField<T>
* [MESOS-2265] - Introduce an os::rename abstraction to stout.
* [MESOS-2266] - Introduce a checkpoint function to support google::protobuf::Repeated<T>

Release Notes - Mesos - Version 0.21.0
--------------------------------------
This release includes several new features.
* State reconciliation for frameworks:
* Allows frameworks to reconcile the states of the tasks.
* Support for Mesos modules

Release Notes - Mesos - Version 0.20.0
--------------------------------------
This release includes a lot of new cool features. The major new features are
listed below:
* Docker support in Mesos:
* Users now can launch executors/tasks within Docker containers.
* Mesos now supports running multiple containerizers simultaneously. The slave
can dynamically choose a containerizer to launch containers based on the
configuration of executors/tasks.
* Container level network monitoring for mesos containerizer:
* Network statistics for each active container can be retrieved through the
/monitor/statistics.json endpoint on the slave.
* Completely transparent to the tasks running on the slave. No need to change
the service discovery mechanism for tasks.
* Framework authorization:
* Allows frameworks to (re-)register with authorized roles.
* Allows frameworks to launch tasks/executors as authorized users.
* Allows authorized principals to shutdown framework(s) through HTTP endpoint.
* Framework rate limiting:
* In a multi-framework environment, this feature aims to protect the
throughput of high-SLA (e.g., production, service) frameworks by having the
master throttle messages from other (e.g., development, batch) frameworks.
* Enable building against installed third-party dependencies.
* API Changes:
* [MESOS-857] - The Python API now uses different namespacing. This will break
existing schedulers, please refer to the upgrades document.
* [MESOS-1409] - Status update acknowledgements are sent through the Master
now. This only affects you if you're using a non-Mesos binding (e.g. pure
language binding), in which case refer to the upgrades document.
* HTTP endpoint changes:
* [MESOS-1188] - "deactivated_slaves" represents inactive slaves in "/stats.json" and "/state.json".
* [MESOS-1390] - "/shutdown" authenticated endpoint has been added to master to shutdown a framework.
* Deprecations:
* [MESOS-1219] - Master should disallow completed frameworks from re-registering with same framework id.
* [MESOS-1695] - "/stats.json" on the slave exposes "registered" value as string instead of integer.
This release also includes several bug fixes and stability improvements.

Release Notes - Mesos - Version 0.19.1
--------------------------------------
* This is a bug fix release.
** Bug
* [MESOS-1448] - Mesos Fetcher doesn't support URLs that have 30X redirects.
* [MESOS-1534] - Scheduler process is not explicitly terminated in the destructor of MesosSchedulerDriver.
* [MESOS-1538] - A container destruction in the middle of a launch leads to CHECK failure.
* [MESOS-1539] - No longer able to spin up Mesos master in local mode.

Release Notes - Mesos - Version 0.19.0
--------------------------------------
* The primary feature of this release is the "Registrar". This is the addition
of replicated state in the master to ensure the set of slaves in the cluster
remains consistent in the presence of master failovers.
* This feature is currently used in a write-only manner by default to allow
smooth upgrades. 0.20.0 by default will be write *and* read.
* Operators must now specify the 'work_dir' for the master, along with the
'quorum' size of the ensemble of masters.
* This means adding or removing masters must be done carefully! The best
practice is to only ever add or remove a single master at a time and to
allow a small amount of time for the replicated log to catch up on the new
master.
* Authentication support has been added for slaves.
* Metrics reporting has been overhauled and is now exposed on /metrics/snapshot.
* Support for external containerization strategies has been added to support
custom container needs as well as experimentation; this is an alpha release!
* There are also several bug fixes and stability improvements.
